Abstract
The fundamental active photonic dimer consisting of two coupled quantum well lasers is inves-
tigated in the context of the rate equation model. Spectral transition properties and exceptional
points are shown to occur under general conditions, not restricted by PT-symmetry as in coupled
mode models, suggesting a paradigm shift in the field of non-Hermitian photonics. The opti-
cal spectral signatures of system bifurcations and exceptional points are manifested in terms of
self-termination effects and observable drastic variations of the spectral line shape that can be
controlled in terms of optical detuning and inhomogeneous pumping.
